“He had winemaking equipment”

Kowalski's mother

Despite the evidence, Kowalski's mother claims the son was only making wine.

She told the Chicago Tribune: "He had winemaking equipment."

She also reportedly said she didn’t know how cops could confuse the carboys and pipettes used in winemaking for the beakers and other materials used in a meth lab.

Kowalski was arrested in 2014 and marked the second time in less than a year a suspected meth lab was found in his home, police said.

He was charged with two counts of possession of a controlled substance, possession of methamphetamine manufacturing materials, and possession of methamphetamine precursors, and a misdemeanour count of possession of drug paraphernalia.

A judge sentenced him to two years of probation and 30 hours of community service.
